Best bang for buck 840$ build?

[Virosa]

My friend want to order a new computer for his girlfriend and he want to do it asap.

The only constraint is 800$ to 840$ Including Shipping. The computer must be built from scratch.(We will build it from the pieces we order). Edit: We are in Canada.

The goal is getting the best gaming performance possible AND for the computer to look cool. She prefer Blue.

to make the inside ofthe case glow blue. there also vendors on ebay that sell 5-6 led connectted to a standard computer molex connector.
